As a lifelong pinball junkie, this goes on my must-see list too.
Before misspending my adulthood on gambling, my youth was misspent on Bally, Williams, Stern, et al.
In younger days I had three games in the living room -- Twin Win, Monte Carlo, and Elektra.
I actually attended the PBF in 1990 in Scottsdale AZ.
Local news interviewed me. And the groupies . . . .
If nothing's changed in sixteen years, you can expect to find many long-lost favorites to play free, in excellent shape, including very rare ones.
Of course, you can always truck a couple three home, if your living room allows.
